Solid hardwood millwork
Your premier source for exceptional millwork & moulding.
Milled, stained, and finished under one roof in New Holland, Pennsylvania — and delivered ready to install, for over thirty years.
The Diamond approach
Interior trim, taken to an exceptional level.
Diamond Millwork is a family-owned business serving the Mid-Atlantic for more than thirty years — a preferred provider of premium, solid hardwood millwork for cabinet makers, kitchen designers, architects and builders.
We take a unique approach to millwork: we manufacture, stain, and finish all under one roof. The result is quality moulding that arrives ready to install, saving our clients valuable time.
This commitment to quality and service stems from a time-honored tradition, passed on through three generations — and on to each and every Diamond Millwork client.
What we do
We mill it, finish it, and ship it ready.
01
We Mill It
Crown, base, casing, and fully custom profiles cut from premium solid hardwood, never composite or finger-jointed filler.
02
We Stain & Finish It
Color-matched staining and finishing happen in-house, so every length arrives factory-consistent, no surprises on site.
03
It Ships Ready to Install
Moulding leaves our shop finished and ready to hang, saving your crew days of prep and protecting your margins.
Why Diamond Millwork?
Reasons the trade keeps coming back.
1. Solid hardwood, always
Oak, maple, poplar, cherry and more — real lumber milled to spec, not wrapped MDF.
2. Everything under one roof
Mill, stain, and finish in one shop means tighter tolerances and one point of accountability.
3. Three generations of craft
A family trade passed down for over thirty years, serving the Mid-Atlantic build community.
4. Built for the trade
Cabinet makers, kitchen designers, architects and builders rely on us to arrive ready to install.
